I've been running fine for the last 4 months but as of two days ago, I just stopped getting any work units. Figured I'd wait a while to see if it was just temporary but still nothing. I uninstalled and re-installed with the public beta 7.4.2 hoping that would help, but I still keep getting the error "Failed to get ID from 'assign4.stanford.edu:80': 10002: Received short response, expected 8 bytes, got 0"

I don't appear to be having trouble pinging any of the active assignment servers but I just don't know enough about whats going on to figure out where the problem is.

Other things I've tried hoping it would help get an assigned work unit but doesn't seem to help.

Could you please lower the verbosity level to 3 (the default) since with verbosity level 5, it prints all values which makes it very difficult to see what values were changed. With verbosity level 3, only the values changed from the default settings are printed so it makes it very easy to troubleshoot.

What happens when you enter http://assign3.stanford.edu:8080/ into your browser? A white page with OK should show up (it does on my system). Also, have you configured the Firewalls and/or Anti-malware/spyware/adware applications to allow F@H to communicate to the servers? A recent update in any of the security applications could cause an issue so you may want to recheck it.

When I try to go to the assign3 webpage, I get some kind of airOS login screen. on port 80 I get an OK but 8080 gets the login prompt.

I've always run with the firewall off but after disabling avast I did get a change in the error. Now I get the " No connection could be made because the target machine actively refused it." so maybe we're heading the right direction.

Here's the log without all the other data in it. Sorry, I figured that more was better.

Windows auto updates unless you turn it off, same with many AV programs. The next update of any of those could suddenly start interfering with FAH. Apps suddenly start running in sandbox mode and can't connect. Not often, but it happens. Even home networking hardware updates itself now.

Reinstalling fah is rarely the fix because it's rarely the problem, so no need to waste time doing that.

I am not sure would say that, from personal experiance if a reboot of the computer does not fix fah when I have a connection problem with v7 a complete removal and renstall then reboot will fix the problem. But that is just my personal experiance others may be diffrent.

Don't worry about assign4. It is a new server which is still being outfitted for future use. The latest versions of client have been prepared to support it whenever it's ready to be enabled but there's still work to be done on the back-end.

Changes to the system...There was a bunch of Win7 updates around 3 days before the problem surfaced, but I did pick up work units after those were installed. NOD32 updates the virus definitions a couple of times a day, but I have tried both white listing Stanford sites and also disabling NOD32 with no success.

In a browser I still get OK from assign3 on 80 but an error from assign3 on 8080.

Could you please lower the verbosity level to 3 (the default) since with verbosity level 5, it prints all values which makes it very difficult to see what values were changed. With verbosity level 3, only the values changed from the default settings are printed so it makes it very easy to troubleshoot.

I can access http://assign3.stanford.edu:8080/ without any issue (white page with "OK" in black colour). Has anything recently changed on your system, an application updated, you installed a new software, etc? Have you rebooted the router?
